Let's divide 57871146 by 142
Let's see how many times 142 fits into 57871146.

On to step 1:
142 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 142

Going ahead to step 2:
57 divided by 142 is 0 with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Append the next digit (8) from the dividend to 57 and continue with: 578 / 142

Advancing to step 3:
When dividing 578 by 142, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 568 from 578 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 142

Going ahead to step 4:
107 divided by 142 is 0 with a remainder of 107.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 107 to get 107.
Append the next digit (1) from the dividend to 107 and continue with: 1071 / 142

Advancing to step 5:
1071 divided by 142 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 407.0
Subtracting 994 from 1071 leaves us with 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 142

Moving on to step 6:
If we divide 771 by 142, we get 5 and a remainder of 61.
The number 5 becomes the next digit in our result. 
Result so far: 4075.0
Subtracting 710 from 771 leaves us with 61.
Include the next digit (4) from the dividend after 61, then repeat: 614 / 142

Moving on to step 7:
614 divided by 142 is 4 with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 40754.0
The remainder is 46 after subtracting 568 from 614.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 142

Going ahead to step 8:
142 goes into 466 3 times with a remainder of 40.
The next digit of our result is 3. 
Result so far: 407543.0
Subtracting 426 from 466 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
142 goes into 400 2 times with a remainder of 116.
Put 2 as the next digit of the answer. 
Result so far: 407543.2
If we take 284 away from 400, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 10:
When dividing 1160 by 142, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 407543.28
Subtracting 1136 from 1160 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
The number 142 fits into 240 1 times, leaving a remainder of 98.
Write down 1 as next digit of the result. 
Result so far: 407543.281
Subtract 142 from 240 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 12:
When dividing 980 by 142, we get 6 with a remainder of 128.
Use 6 as the next digit of our solution. 
Result so far: 407543.2816
If we take 852 away from 980, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 13:
The number 142 fits into 1280 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 407543.28169
If we take 1278 away from 1280, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
142 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 407543.28169
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 15:
200 divided by 142 is 1 with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 407543.2816901
Subtract 142 from 200 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 16:
When dividing 580 by 142, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 407543.28169014
If we subtract 568 from 580, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 407543.28169014, with a leftover of 1.2e-08.
